      "使用Redis的List结构，通过LPUSH和LRANGE来管理一个会话的所有消息。",
      "使用Hash结构存储单个会话，键名为`chat:history:{chatId}`，Hash的field为消息ID，value为序列化的消息对象。"
    ],
    "correctAnswerIndex": 3,
    "explanation": "文档在“Redis键值设计最佳实践”一节中明确指出，推荐使用Hash结构来存储每个会话的所有消息。具体的键命名规则是`chat:history:{chatId}`，其中Hash内部的field是唯一的消息ID，value是序列化后的消息体。这种设计便于对单个会话内的消息进行增、查、改、删操作。",
